I had protruding canines ie. vampire teeth on my upper jaw.

I had braces for my upper jaw, and extracted two teeth to make space.
I think I wore retainers for almost 6 months in the beginning to pre-move the teeth and later almost 2 years of permanent braces and then another year of retainers to make sure that they don't move after the braces were removed.

Never regretted having them on because the difference is really alot after having braces, and my teeth now look so much better than they were before and furthermore I had it done in the governemnt hospital, and since my mum is a government servant, I got it done for free.

My advise, go for it if you have the chance/opportunity, so far I havne't heard of anybody who wasnt satisfied with the outcome.

However, few things to keep in mind. Your oral hygiene during the duration of the treatment must be good because naturally bits and pieces of food will get stuck and try to brush as often as possible.

Do not be lazy in wearing your retainers, they do help in the treatment.

Be prepared to endure some ulcers and cuts in the inner mouth due to them being brushed by the wires and studs.

And of course, keep to your dentist appointment.
